The world's SECOND pregnant man is 'blissfully happy' as he prepares to give birth to baby boy next month






A transgender couple have revealed they are expecting their first baby in a month’s time.
Scott Moore - thought to be only the second ‘pregnant man’ to go public - is due to give birth to a boy in February, with husband Thomas by his side.
The couple were both born girls and have undergone surgery to transform their sex.


Scott, 30, who is legally married to Thomas because he still has a female birth certificate, says he is eagerly looking forward to giving birth.
They have decided to call the child ‘Miles’.
‘We know some people will criticise us but we are blissfully happy and not ashamed,’ Scott said.
The couple, from California, already have two children - Gregg, 12, and Logan, 10 - who Thomas had with a previous female partner.
The case is similar to that of Thomas Beatie, from Oregon, who made headlines around the world in 2008 when he gave birth to a girl.



Scott, who started out in life as a girl named Jessica, first realised he wanted to be a man when he hit puberty aged 11.
‘When I told my family they thought I was crazy but they gradually realised I was serious and allowed me to start taking male hormones when I was 16 years old,’ he said.
His parents paid £4,600 for Scott to have his 36DDD chest removed. However, he could not afford the gender surgery, so still has female organs.
Thomas, who used to be called Laura, had a hysterectomy and gender reassignment surgery last year.



They met in 2005 at a support group meeting for transgender men but lost touch – but saw each other again in 2007.
‘We knew we had to be together,’ Scott said. ‘Two months later I gave up my job to live with Thomas and the boys.
‘Now they call me “dad two”.’The couple, who live in a four-bedroom house, decided in December 2008 to try for a baby.
Scott was inseminated with the sperm of a male friend and fell pregnant in June 2009.
‘We were so happy we did what all gay men do when they get excited - we went shopping,’ Thomas said.


The couple have dismissed concerns that Miles might be teased at school, saying they are confident they can deal with it.
‘We've been through it already,’ Thomas said.
‘My son Logan was bullied but now he just says to teasers: “You may have a problem with my two dads but I don't so you're not hurting me”.’
Scott plans to have a natural birth at their local hospital. Their doctor and obstetrician have told the medics at the local hospital.


We didn't want everyone to be shocked when a man turns up to give birth,’ Scott said.‘We found it very difficult to get a doctor and midwife at first. It was hard when people didn't want to treat me.
‘No pregnant person should be denied healthcare just because they are a man.’
But he added: ‘I'm looking forward to giving birth now. With Thomas at my side everything will be just fine.’
Thomas said: ‘We want to show the world that trans-families can be healthy, loving and nurturing.’

Pictured: The schoolgirl who 'cries' blood and bleeds through her pores



American expert Dr George Buchanan observes Twinkle bleeding from her eyes at the Jaslok Hospital in Mumbai.Unique case: Twinkle Dwivedi has an undiagnosed disorder which means she loses blood through her skin without being cut or scratched




A schoolgirl who spontaneously bleeds from her pores has left doctors baffled.

Indian Twinkle Dwivedi, 14, has an undiagnosed disorder which means she loses blood through her skin without being cut or scratched.

The teenager, from Lucknar, Uttar Pradesh, has even undergone blood transfusions after bleeding from her eyes, nose, hairline, neck and soles of her feet about 50 times each day.
She said: 'I bleed from my eyes, my hands, my head, from everywhere. From my ears, nose and eyes as well.

'It doesn't hurt when the bleeding starts. But it makes me tired and sometimes I have headaches.'

Dr George Buchanan, a leading American paediatric blood specialist who has worked in Britain, travelled to India to look into Twinkle's case.

He visited her family at the Jaslok Hospital in Mumbai where he observed her bleeding.

He said: 'I've never seen a case of someone who bleeds spontaneously from their scalp or their palms, or read about it in medical history.

'I was interested to see if I could help Twinkle.'

The doctor was called to the family's hotel room to witness bleeding which began from her hair parting. He was shocked to find no signs of cuts, bruising or redness.

Dr Buchanan said: 'It doesn't seem physically possible for blood to seep through intact skin.

'But I saw no signs of cuts or bruising anywhere on her body.'

Twinkle's mother Nandani Diwedi, 43, who runs a beauty salon as well as caring for her four daughters, said: 'We have tried praying and seeking medical help to cure Twinkle. Sometimes you need to do both.

'It hurts me to see her like this. I share her pain.'
Dr Buchanan and his team carried out a series of tests including cutting Twinkle's skin to time how quickly the bleeding stops.

Tests show she may have a mild form of a clotting disorder, which means her platelets do not stick together properly. But this is not enough to explain the spontaneous bleeding.

Dr Buchanan is also investigating whether Twinkle or her mum cause the bleeding themselves.

Twinkle, a Hindu, said: 'I am not causing this. Why would I want to make myself bleed?

'I don't want to be like this. I want to go to school and have a normal life.'

She has missed at least two years of education after two schools banned her from classes because of the bleeding.

Her father Aditya Kumar Diewdi, 48, a railway worker, said: 'This is very frightening for my family. We just want to help Twinkle get better.'

Specialists are now planning 24hour monitoring of Twinkle so close-up surveillance cameras can record exactly how the bleeding begins.

Dr Buchanan said: 'There is a healthy relationship between Twinkle and her mother.

'My heart tells me this may be is a condition we have never seen before.'

The mysterious case of Twinkle's bleeding is fully examined in a new BodyShock documentary, The Girl Who Cries Blood, due to air on Channel 4 at 10pm tomorrow.

It also shows Twinkle's family visiting a local mystic, being examined by a Christian bishop for stigmata, and bathing in the River Ganges.

Last year an American boy, Calvino Inman, 16, from Rockwood, Tennessee, also began bleeding from his eyes, and his case is now under investigation by doctors in the US.

Iran blames 'U.S. and Zionists' after top nuclear scientist is killed by remote-controlled motorcycle bomb -US denies 'absurd' claim of role in Iran bombing

ran has blamed the U.S. and Israel for the assassination of one of the country's top nuclear scientists.

Massoud Ali Mohammadi was killed this morning by a bomb-rigged motorcycle parked outside his Tehran home.

He has just left the house on his way to work when the remote-controlled explosion went off.

Websites linked to the country's clerical leadership blamed the killing on an armed Iranian opposition group under the direction of Israeli agents.

But Massoud Ali Mohammadi was a vocal supporter of opposition leader Mir Hossein Mousavi after the disputed presidential election result last June.

The blast shattered the windows of Mohammadi's home in northern Tehran's Qeytariyeh neighborhood and left the pavement outside smeared with blood and strewn with debris.

It is unclear whether the 50-year-old was actively involved in the Atomic Energy Organisation of Iran, which controls the country's nuclear programme.

'Signs of the triangle of wickedness by the Zionist regime (Israel), America and their hired agents, are visible in the terrorist act,' the Foreign Ministry said.

'Such terrorist acts and the apparent elimination of the country's nuclear scientists will definitely not obstruct scientific and technological processes,' it added.

A US government spokesman described the accusations as 'absurd'.
Another Iranian nuclear scientist, Shahram Amiri, disappeared in June while on a pilgrimage to Saudi Arabia.

Amiri's disappearance raised questions about whether he defected and gave the West information on Iran's nuclear program, but Iran's foreign minister accused the U.S. of helping to kidnap him and asked for his return.

Amiri worked at a university linked to the elite Revolutionary Guard military corps and his wife said he was researching medical uses of nuclear technology at a university.

In 2007, state TV reported that another nuclear scientist, Ardeshir Hosseinpour, died as a result of gas poisoning.

A one-week delay in the reporting of his death prompted speculation about the causes, including that Israel's Mossad spy agency was to blame.

The United States and its allies in Europe have been pushing Iran to halt its uranium enrichment program, a technology that can be used to make fuel for power plants but which also offers a possible pathway to weapons development.

Israel has threatened to take military action if diplomatic efforts fail.
U.S. Secretary of State Hillary Rodham Clinton yesterday said the Obama administration has concluded that the best way to pressure Iran to come clean on its nuclear ambitions is to impose sanctions aimed at the country's ruling elite.

'It is clear that there is a relatively small group of decision makers inside Iran,' Clinton told reporters traveling with her on the first leg of a nine-day trip across the Pacific.

'They are in both political and commercial relationships, and if we can create a sanctions track that targets those who actually make the decisions, we think that is a smarter way to do sanctions. But all that is yet to be decided upon.'

Iran is already under three sets of U.N. sanctions for refusing to freeze its enrichment work.

On Tuesday, a spokesman for Iran's Foreign Ministry, Ramin Mehmanparast, told reporters that sanctions would not work.
'This is not a constructive attitude,' he said. 'I do not think the issue can be solved this way. Instead, our nuclear rights should be respected.'

Tehran prosecutor Abbas Jafari Dolatabadi confirmed that Ali Mohammadi had been killed and added that there had been no arrests.

Iran denies having any intention to produce weapons and insists its nuclear work only has peaceful aims, such as energy production.

Mohammadi was the author of several articles on quantum and theoretical physics in scientific journals.

He also was a member of some academic associations focusing on experimental science, but he did not appear to have any high-profile role in promoting Iran's nuclear programme.

He received his doctorate in 1992 from the Sharif University of Technology in Tehran.

The assassination of one of Iran's nuclear scientists is an indication of the country's advancement in different scientific fields, the head of a leading scientific establishment in the capital said Tuesday.

Professor Masoud Ali-Mohammadi, a lecturer at Tehran University, was killed by a booby-trapped motorbike blast in the Iranian capital earlier in the day. The explosion took place near the professor's home in the Qeytariyeh neighborhood of northern Tehran.

"Our scientific expertise has prompted our enemies to target our scientists," Mohammad-Javad Larijani, who heads the Institute for Research in Fundamental Sciences, said.

Ali-Mohammadi had cooperated with the institute that offers various advanced PhD degrees in areas such as Mathematical Logic and Plasma Physics among others.

The enemy, the Berkeley-educated mathematician said, has made a colossal mistake as the death of one scientist will only motivate tens of other Ali-Mohammadi's to rise in his place.

Iran's Foreign Ministry said that it found traces of US and Israel's involvement in the assassination of an Iranian nuclear physics scientist.

"Primary investigations into the assassination revealed signs of the involvement of the Zionist regime [Israel], the US and their allies in Iran," ministry spokesman Ramin Mehman-Parast said.

Mohammad Marandi, a professor at Tehran University, told Press TV that Ali-Mohammadi's colleagues at the capital's most prestigious university believe the attack was orchestrated by the West.

"It is widely believed among collogues that he was assassinated by terrorist organizations probably supported by the United States and with connections with the Americans and the Israelis under different names," he said.

"Unfortunately when it comes to Iran anything is acceptable in the eyes of the foreign powers."

Mystery of Death Valley's gliding rocks-Stones roll itself in dry deserts.


One of the extraordinary moving rocks leaves a track through Death Valley

Rock on: More of the boulders and the eerie paths they leave across the Valley


These extraordinary pictures reveal a bizarre event that is puzzling the science world - rocks that glide across the desert.

Amid the eerie silence and the 50C heat of California's Death Valley these giant boulders appear to move smoothly - and unaided - across the desert.

The rocks, some as heavy as 17 stone, edge along in bizarre, straight-line patterns across the ultra-flat surface of the valley. They can travel more than 350 yards a year.


Scientists believe the phenomenon is caused by a coming together of specific weather conditions.

Studies suggest a combination of 90mph winds, ice formations at night and thin layers of wet clay on the surface of the desert all help to push them along.

Photographer Mike Byrne, 40, has spent years documenting the stones' mysterious movements.



As his amazing pictures show these real-life rolling stones leave trails across the sand in places almost untouched by man.

He said: 'Some of these rocks are as heavy as a person, it is really is strange to imagine them gliding across the desert like this.

'They must be the original real-life rolling stones, they just keep moving through the sand and I don't believe anyone has really 100 per cent worked it out yet.



Most of the stones are found on an old lake bed, known as the Racetrack Playa, where the ground is particularly flat.

'It has been documented over the years and it is something very special to witness, although I know climatologists believe the phenomenon could disappear in a few years as the temps continue to rise.

'One of the strongest theories about what the rocks move is that water rising from beneath the surface of the sand is pushed by the wind creating a surface the rocks can move along.'

Death Valley is the lowest point in the U.S., at 282ft below sea level.

It is almost completely flat and holds the record for the second highest temperature ever recorded on earth, a blistering 58C.

In the 1990s a study by a team of scientists lead by Professor John Reid, from Hampshire College, Massachusetts, attempted to explain the rocks' movement.

His study concluded that the rocks may be moved when they become embedded in sheets of ice forming at night on the surface of the sand.

As the sand melts Prof Reid said that the rocks were moved along by the ice and wind, thus forming the patterns.

Water On The Moon: LCROSS Kicks Ice!- Buckets of water found in Moon .


Space enthusiasts in California watched the mission live last month


Impact: This Nasa image shows the flash of light as the rocket struck the lunar surface last month. Scientists today revealed they found a 'significant' amount of water in the debris

This is the first image of the moon taken from the satellite on its approach last month. Two Nasa spacecraft then barrelled towards the moon at twice the speed of a bullet

Nasa has found 'a significant amount' of water inside a crater on the Moon in a discovery that could pave the way for the first manned lunar base.

The agency announced that last month's audacious attempt to smash two spacecraft into the Moon's rocky surface to find ice was a major success.

The £49million bombing raid threw up a mile-high plume of dust - which included chunks of ice locked away in a deep crater at the lunar south pole. The bottom of the crater had not seen sunlight for billions of years.

The revelation may bring closer the day when mankind creates a permanent lunar base, using the water buried in the rocks to drink and generate hydrogen fuel.

A spokesman for Nasa said last night: 'The discovery-opens a new chapter in our understanding of the Moon.'

There were fears that last month's experiment had failed when the collision of the two spacecraft failed to produce the expected six-mile-high cloud of dust. Live pictures relayed from the Moon showed no sign of an impact, even though the crafts crashed as planned.

But yesterday, Nasa experts who studied the data said instruments trained on the impact saw a significant amount of water vapour.

Dr Anthony Colaprete, from NASA's Ames Research Centre, said: 'Indeed, yes, we found water. And we didn't find just a little bit, we found a significant amount. We are ecstatic.'

Michael Wargo, chief lunar scientist at Nasa headquarters in Washington, added: 'We're unlocking the mysteries of our nearest neighbour and by extension the solar system.

'It turns out the moon harbours many secrets, and LCROSS has added a new layer to our understanding.'

The LCROSS mission, which took place on October 9, was watched by millions across the globe live on the internet.

One rocket slammed into the Cabeus crater, near the moon's southern pole, at around 5,600mph, and was followed four minutes later by a spacecraft equipped with cameras to record the impact.

Over the last decade, scientists have found some hints of underground ice on the moon's poles, but this is the best evidence yet.

The discovery is expected to have major implications for the future of lunar exploration, and a ready supply of water could facilitate lunar bases.

Astronaut Buzz Aldrin, who in 1969 made his historic Apollo 11 moonwalk with Neil Armstrong, was pleased to hear the latest discovery, but still believes the U.S. should focus on colonizing Mars.

'People will overreact to this news and say, 'Let's have a water rush to the moon,"' Aldrin said. 'It doesn't justify that.'

Mission scientists said it would take more time to tease out what else was kicked up in the moon dust.

NASA probes give moon a double smack


This image provided by NASA shows an image taken shortly after the Centaur rocket impacted the moon taken from the Lunar Crater Observation and Sensing Satellite Friday morning Oct. 9, 2009.



This still image from the 1902 silent film "Le Voyage Dans La Lune", written and directed by Georges Méliès, shows "the man in the moon" with a bullet-shaped space capsule lodged in his eye. For as long as man has looked up, the moon has inspired romance, poetry and songs. Man also likes blowing things up. Now we get to do both



This still image from the 1902 silent film "Le Voyage Dans La Lune", written and directed by Georges Méliès, shows "the man in the moon" with a bullet-shaped space capsule lodged in his eye. For as long as man has looked up, the moon has inspired romance, poetry and songs. Man also likes blowing things up. Now we get to do both



NASA smacked two spacecraft into the lunar south pole Friday morning in a search for hidden ice. Instruments confirm that a large empty rocket hull barreled into the moon at 7:31 a.m., followed four minutes later by a probe with cameras taking pictures of the first crash.

But the big live public splash people anticipated didn't quite happen. Screens got fuzz and no immediate pictures of the crash or the six-mile plume of lunar dust that the mission was all about. The public, which followed the crashes on the Internet and at observatories, seemed puzzled.

NASA officials said their instruments were working, but live photos of the actual crash were missing. Some select photos should be ready by a 10 a.m. press conference, they said.

But so far all NASA had was "images on the way in," said NASA spokesman Grey Hautaluoma.

Expectations by the public for live plume video were probably too high and based on pre-crash animations, some of which were not by NASA, project manager Dan Andrews told The Associated Press Friday morning 80 minutes after impact.

The first and much bigger crash was supposed to hit with the force of 1.5 tons of TNT into crater Cabeus and create a mini-crater about half the size of an Olympic pool. The second crash was to be about one-third as strong.

The idea is to confirm the theory that water — a key resource if people are going to go back to the moon — is hidden below the barren moonscape.

The images were to come from the probe itself. The probe is LCROSS, short for Lunar Crater Observation and Sensing Satellite and pronounced L-Cross. It had five cameras and four other pieces of equipment to look for ice or any form of water as it dove through the dust storm created by the empty hull.

Minutes before the first crash, NASA was riding high, reporting no trouble at the Ames Research Center in California, where the mission was being controlled.

"Everything is working so very well," NASA's Victoria Friedensen, a manager in NASA's exploration office, said minutes before the one-two smack.


"What matters for us is: What is the nature of the stuff that was kicked up going in?" Andrews said. "All nine instruments were working fine and we received good data."

Andrews said the science team is pouring through the information — including what are supposed to be good images from ground-based telescopes on Earth — to answer the big question: Is there some form of water under the moon's surface that was dislodged? It will probably be two weeks before scientists will be certain about the answer, he said.
